I need to know the exact manner by which my iPhone will interface with Google Mail. Specifically, deletion of mail on my phone affects my gmail how, etc. Does deleting it on my phone affect my account, if so after any length of time? And so on, as much information as possible on the matter, please. I've taken to using the iPhone for work, so the answers to these questions interest me greatly.
I've seen threads which allude that it may be impossible to not cc's of the mail you send, but if anyone has suddenly come to the epiphany on the matter I would be grateful.
